The article embodyin the present inventlon 1s so formed that 1t may be cut from a sin le inte' ral sheet of paper and then folde in a simplepand convenient manner to form the envelop and the cup inclosed thereby. The article ,comprises essentially an envelop portion indicated in general by the reference letter A and a cup ortion indicated bythefkreference letter Of the envelop portion, the numeral 1 indicates the front and the numeral 2 the back, these portions being of the usual rectangular outline and of any desired size. Integral with one end edge of the front 1 is a permanent closure iap indicated by the numeral 3, this ap being gummed upon its inner face as` indicated by the numeral 4, so that when the back 2 is folded over to'confront the front 1,*the said flap 3 may be folded down 'upon the outer face of the saidback 2 and secured by the adhesive. The said fr'ont l is provided atl its opposite end `edge with an integral closure flap 5 having a locking tongue 6 of any suitable contour, and` the back 2 is formed with a slit,7 intoY which the locking tongue 6 may be inserted for the purpose of securing the closure fiap 5 in position closingl the mouth of the envelop. As will be presently explained, the closure .Hap 5 serves also as a protecting and closing iap for the .mouth of the drinking'cup in the completed condition of the article. The numeral`8 indicates a temporary protecting iiap which is integral with Athat end edge of the back 2 corresponding to theedgel with which the flap 5 vis integral.

The cup portion of the article includes a side 9 and a side 10 and the latter vside is provided at its outer longitudinal edge with an integral iap 11 one face of whichis provided with an adhesive coating indicated by the numeral 12. Also the inner face of4 the side 9 at that end corresponding to the end of the front lof the envelop portion with which the flap 3 is connected, is provided with a narrow area of adheslve indicated by the numeral 13.

In Vfolding up the blank from which the article is to be formed, the said blank is folded along the line of juncture of the front 1 of the envelop portion with the side 9 of lthe cup portion and said cup portion is'folded along the line of juncture of 1ts sides 9 and 10 and also along the juncture of the Hap 11 with the said side 10: The gummed side 12 of the said flap 11 is then caused to adhere to the inner face of the side 9 of the said cup portion and the adhesive area 13 is caused to adhere to the inner face of the said side 10, thus forming a cup the mouth of which is indicated by the numeral 14. After having thus formed the cup ortion of the article, the said cup portion 1s folded bodily to lie against the inner face of the front 1 of the envelop, after which the back 2 of the envelo portion is folded over and secured by its a hesive coating indicated by the numeral 15, to the outer face of the side 9 of the said cup portion. Finall the flap 3 is folded over and its adhesive earing side is secured to the outer face ofthe back 2 of the envelop portion.

By reference to the drawings it will be observed that the adhesive coating 15 extends substantially over the entire area of the inner face of the back 2 of the envelop portion except that in an area, indicated by the numeral 16, in which the slit 7 is located, the adhesive coating is not applied so that a pocket is formed between the said back 2 of the envelop portion and the side 9 of the cup portion in which the locking tongue 6 of the flap 5 may be received. Having folded up the article in the manner stated above, the ap 8 is to be folded inwardly over the mouth of the cup so as to efectually close and protect the said cup. The article is then in condition to receive the mail matter to be transmitted, and such matter is of course, inserted between the side 10 o the cup portion and the front 1 of the envelop portion. After the matter to be transmltted has been placed within the article, the closure flap 5 is to be folded over and secured by the insertion of the locking tongue 6 through the slit 7.

After the article has served its purpose as a mailing envelop the recipient will tear olf the flap 8 which, in the transmittal of the article through the mails, has protected the mouth of the drinking cup. Then the article may be employed `as an ordinary paper drinking cup and after use the closure flap 5 may be turned down and locked in place so as to efectually protect the mouth of the cup. Of course, the sides 9 and 10 of the cup will be suitably water-proofed, as for example, by a coating of aralin.

It is preferable that the locking tongue 6 be of t e shape shown in the drawings, the said tongue comprising a relatively wide body ortion 17 having rounded margins 18, and a relatively narrow neck 19. This tongue is bifurcated or formed with a slit 20 extending inwardly from its outer edge and to or slightly inwardFly beyond the n eck 19, as clearly shown in ig. 5. The slit 7 which receives the tongue 1s preferabl of a length substantially equal to the. Widt of the neck 19 and consequently of a len h less than the maximum wldth of the bo y portion 17 of the tongue and therefore when the neck 19 is Within the slit 7 the tongu will expand and will be ei'ectually loc against Withdrawal until the portions are again moved together as the tongue is being withdrawn.

Itis preferable that the front of the article be provided with a transparent area or window 21 which ma extend over a part or the entire area o the' said front and through which the name and addressof the addressee `may be visible, or, where the entire surface is transparent, not only will the name and address be visible, but the letter head will also be visible and may therefore serve the purpose of the usual return card.
